I picked up a used Kenworth air horn cheap off of eBay (really used - still had a chunk of fiberglass attached). I also picked up a new 12/24 volt solenoid to run the horn. I put it in the cab at the end of a t fitting under the dash on the right side. Then I mounted the horn on the right side inner fender well and plumbed copper line to it. A quick call to DH and I found a spot to tap into some electricity. The test went well, the truck had about 50 psi in it and the horn was pretty loud. I wanted to see if the horn was louder than the truck so I fired her up and tried again. It got even louder, BUT the thing won't shut off after 60 PSI. I need an American made, non eBay solenoid. Can any recommend a good one or a place to find one? I should have known better than trying to go cheap. My truck runs with 90-100 psi so it will have to be able to hold that.
